Heating & A/C (A7)Câu 83 / 120
The evaporator in the passenger compartment:
a.Compresses the refrigerant
b.Rejects heat to the outside air
c.Stores excess refrigerant
d.Absorbs heat from cabin air, cooling it
Giải thích
As low-pressure liquid refrigerant boils in the evaporator, it absorbs heat from the cabin air blown across it, cooling and dehumidifying the air. A restricted or iced evaporator reduces airflow and cooling. Proper refrigerant charge and airflow keep it working correctly.
